No. 174,617 Claims priority, application Germany Feb. 23, 1961 a Claims. (Cl. 68-43) The present invention concerns a washing or dyeing machine for web-like textile materials which are passed in loops through vats provided with vibrators.

In such installations it is known for the intensified through flow of the fabric webs to be washed out or dyed to provide beating rollers between adjacent webs making contact therewith and acting as vibrators. Such rollers may comprise eccentric discs or such having an oval cross-section which impact the material passing them thereby imparting thereto an additional cross-movement in the washing water or the dye liquor. When washing, it is necessary to renew at least partly the washing water after a certain operating period, to avoid a harmful concentration with washed out chemicals.

It is an object of the invention to improve substantially the efiiciency of such installations, in that the washing effect of the vibrators used is increased, not only by a favourable mechanical construction but also by the fact that the vibnator is operated ina region of fresh water supplied under pressure, This causesin addition an increased stretching elfect to be produced on the fabric by the strong flow occurring outwardly due to the closely adjacent fabric webs and a crease-free operation is thus ensured.

According to the present invention, a washing or dyeing machine for textile fabric webs which are passed in loops through vats provided with at least one vibrator, is characterised by the feature that the or each vibrator is mounted on a hollow shaft through which a fresh water supply is adapted to pass, a roller body studded with rows of teeth and having radially arranged outlet openings being provided on the or each hollow shaft, the tips of the teeth being adapted to contact adjacent fabric webs.

The roller body may have an oval cross-section and be provided with a star profile pipe for forming the rows of teeth, and outlet openings and be held by end flanges. The rows of teeth may also be formed by alternately staggered discs between which the outlet openings are provided.

The shaft with the vibrator is conveniently guided on both sides of the washing vat in bearings provided with stufiing boxes and so constructed that the drive is effected from one side and the water supply arranged on the other side; therefore it is also possible for the driven side of the shaft to be solid.

A disengaging device for the material webs is arranged which is normally supported against both sides of the vibrator, conveniently comprising a pair of rollers prefenably arranged above the vibrator and adapted to be swung about a pivot situated between two rollers from a vertical inoperative position into an inclined up to horizontal operative position. This may be caused by means of a lever arm adapted to be continuously adjusted along a cam guide.

The invention will now be described furthertby way of example, with reference to the accompanying drawings, in which:

FIG. l is a schematic view showing the course of a fabric web from the inlet frame in a first washing vat of the washing installation;

FIG. 2 is a schematic view of two adjacent fabric webs with a vibrator and removing rollers situated therebetween;

FIG. 3 is a longitudinal section through the vibrator;

FIG. 4 is a perspective view of a radial profile suitable for forming the rows of teeth of the vibrator.

FIG. 1 shows a washing installation; a fabric web 2 arriving via several guide and reversing roller is drawn oif by an inlet squeezing mechanism 3 and, by means of a compensating roller 4, arrives in the first washing vat 5. Usually the fabric web 2 passes through several identical washing vats arranged one behind the other (not shown).

Each washing vat has a system of reversing rollers provided therein, thereby causing the fabric webs 2 to travel along a path which is as long as possible through the washing water in the vat. The upper rollers 6 thus simultaneously act as driving rollers. Vibrators 9 are inserted at suitable points between adjacent fabric webs 7, 8 tnavelling in opposite directions to improve the flow through the fabric; they are inserted in such a manner that the tips of their teeth contact the adjacent fabric webs 7, 8. v

The vibrator 9 is mounted on a shaft 10 and has a roller body 11 which corresponds in length to the width of the fabric webs. The roller body 11 i studded with rows of teeth 12 which are arranged such that a star profile pipe 30 provided with outlet openings 16, distributed uniformly or at random is drawn onto a bush 15 of the roller body, the outer edges of the pipe forming the rows of teeth 12. v t

In another embodiment, square discs 13, 14 are arranged in succession on the roller body 11 in a correspondingly staggered manner relative to one another. The discs 13, 14 are fixed on the bush 15 in spaced re lationship to one another and the outlet openings 16 formed therebetween. To increase the impact effect the bush 15 can have an oval cross-section. Two end flanges 17 and 18, by means of which the vibrator is connected to the shaft 10, are provided to keep the vibrator parts together. The shaft 10 need be hollow only at one end (in FIG. 3 on the left) and be provided with a coupling 19 for the water supply. The right hand side 10' of the shaft imparts the drive (not shown).

The shaft 10, 10 is guided in front and rear walls, 20, 21 of the washing vat 5 in bearings provided with suitable stufiing boxes 22, 23. When the vibrator 9 rotates, the tips of the successive rows of teeth 12, possibly assisted by the oval shape of the roller body 11, strike against the fabric Webs 7, 8 passing on either side to which they thus impart alternately a greater speed. Moreover not only is there caused a turbulence in the surrounding water, but also simultaneously fresh water is supplied under pressure through the hollow shaft 10 and the openings 16 of the vibrator, so that in the vicinity of the vibrator, washing takes place with practically fresh water. Apart from a particularly intensive through flow of the fabric, an excellent washing effect is obtained.

For carefully handling lighter fabrics, ta disengaging device 26 comprising two parallel rollers 24, 25, is provided above the vibrator 9. The two rollers 24, 25 are so mounted on a fixed axle 27, situated therebetween and acting as pivot, that they are adapted to be mutually swung away by means of an upwardly extending lever arm 28, so that they can be swung out of their inoperative position, in which the rollers are disposed one below the other, into a horizontally inclined operative position. This is indicated in FIG. 2 by chain-dotted lines. The lever arm 28 is adapted to be continuously adjusted along a cam guide 29.

In their operative position, the fabric webs 7 and 8 previously supported closely against the vibrator 9 are disengaged to such an extent that they are clear of the tooth tips of the vibrator and cannot be damaged thereby.

Beating of the fabric webs is then merely carried out by the water movement produced bythe vibrator.
